Robert Plant says that he is certain he will make another album with Alison Krauss. Released in 2007, their "Raising Sand" collaboration won Grammy Awards for "Album Of The Year", "Best Contemporary Folk/Americana Album", "Record Of The Year" for "Please Read The Letter", "Best Pop Collaboration With Vocals" for "Rich Woman", and "Best Country Collaboration With Vocals" for "Killing The Blues".
When asked if there will be a follow-up to "Raising Sand", Plant told Classic Rock magazine: "Oh, I'm sure, yeah. I see Alison a lot and talk to her a lot, and [producer] T Bone [Burnett] too. The reality is that I ran back once before, and [BAND OF JOY bandmate] Patty [Griffin] had made her 'American Kid' record and was touring with that. And I think once you start splintering off and going different ways, and you're a stranger in a place where people still think there’s a mirror ball rotating around your head, it's really good to dig in with the reality of the [SENSATIONAL] SPACE SHIFTERS. There's no greater thing than being on stage when these guys are in full flight."
Back in 2015, Republic Records released the "Love The Coopers" official soundtrack album, featuring the studio reunion of Plant and Krauss on their Christmas original "The Light Of Christmas Day".
In a 2014 interview with Rolling Stone, Plant revealed that he had been talking with Krauss about recording a follow-up to "Raising Sand". "Alison called me six weeks ago," he says. "She said, 'Should we make a new record?'"
Plant previously tried to make a "Raising Sand" follow-up when he and Krauss finished their tour in 2009. The LED ZEPPELIN frontman entered a California studio with producer Daniel Lanois and attempted to write material he could sing with Krauss. "We walked away from that and took our toys back," said Plant. "Dan and I wrote about five songs in two or three days up in Silver Lake. They were pretty good, but they didn't really lend themselves to a vocal collaboration, so I took them away. And then Alison went back to the fat guys with beards [her longtime band UNION STATION] and she made a pretty good record within that genre."
